Excellent source of heat for 2 pallet x 2 pallet covered enclosure/nursery of Pygmy goat kids. Most does would allow week old kids to gather inside during near freezing nights. One tank of fuel would last from 5pm through 9am with fuel left to run longer. Started on level 3 of 6 to preheat enclosure, then run on 1 for the night. Remote is useful. Could use a fuel filter as sediment was noticed in tank bottom. Slots in case allow light in to inspect tank for fuel level and contaminates. We modified legs to stand off ground in event of flammable flooring too near exhaust line. Exhaust line is "very hot", should be positioned to not allow contact with combustibles.
